Abstract
A cup-shaped shield surrounds a counter weight on the lower end of a rotor of the refrigeration compressor. The shield advantageously restricts lubricant flow to the rotating lower end of the rotor whereby power consumption of the motor is reduced. The shield may be axially and/or rotationally limited by engagement with a lower bearing assembly. The shield may be used on a scroll compressor. The shield may also be used on a rotor without having a counter weight on the lower end thereof.
